Dustin Diamond Involved in Celebrity Fit Club Dust-Up

It's chaos on the set of VH1's hit show Celebrity Fit Club, according to TMZ, which has exclusive details on multiple battles raging between its "stars."

According to sources, the first flare-up took place between medical/diet expert Dr. Ian and Ant, the show's host - over a cigarette. Dr. Ian blew up (figuratively) when Ant fired up a Marlboro Light in the doc's vicinity. Britney Spears would be proud.

After the two men were separated, egos were stroked, and both got over the incident, production resumed. But that wasn't all the drama by any means.

Soon after, former Saved By the Bell star and current porn star Dustin Diamond allegedly threatened to "make a dildo of my c**k and f**k" former American Idol star Kimberly Locke with it during a heated altercation.

Gross, dog. It would probably be hotter if it were another Saved By the Bell star threatening another American Idol finalist with this. Like Mario Lopez saying it to Carrie Underwood.

Nevermind, it's still nasty.

According to sources, Locke, along with almost every member of the cast, including pop star Tiffany, rap star Warren G and Brady Bunch star Maureen McCormick all stormed off the set.

Wow. We knew Screech was a sick f**k back when he gave those chicks the Dirty Sanchez, but this is messed up. The producers have reportedly exiled him and he will no longer interact with the cast. No word on whether the cast will watch the Dustin Diamond sex tape instead.

While we applaud Diamond for trying to make things interesting, hopefully the next season of Celebrity Fit Club will feature some more interesting characters. Like Katie Rees, maybe. Or how about David Hans Schmidt. The guy could stand to lose a few pounds.
